/install wgs84
功能描述
Explain and work with the WGS 84 coordinate system for GPS-style longitude/latitude data, including EPSG:4326 usage, axis-order checks, range validation, UTM...
安全使用建议
This skill appears safe and does what it claims: a local Python CLI tool for validating and reasoning about WGS84 coordinates. Before installing, confirm you are comfortable allowing Homebrew to install/upgrade Python on the host (or skip the install if python3 is already available). If you prefer tighter control, inspect scripts/wgs84_tool.py (it only reads CLI args and prints JSON) and verify no external network calls are required for your use. Note the agent config allows implicit invocation (the agent may call this skill when it deems relevant); if you do not want the agent to call skills autonomously, disable implicit invocation in your agent policy. Finally, for file-based bulk reprojection the skill intentionally suggests using QGIS — it does not perform file I/O or batch reprojection itself.
功能分析
Type: OpenClaw Skill
Name: wgs84
Version: 1.0.0
The wgs84 skill bundle is a legitimate utility for validating GPS coordinates and recommending coordinate reference systems. The core logic in scripts/wgs84_tool.py is restricted to mathematical calculations and range checks using standard Python libraries, with no evidence of network access, file system manipulation, or shell execution. The instructions in SKILL.md are strictly aligned with the stated GIS purpose and do not contain any prompt-injection or exfiltration attempts.
能力评估
Purpose & Capability
The name/description (WGS84 coordinate checks and recommendations) matches the included files and required binaries. Requiring python3 and including a small Python script is proportional to the stated functionality. Mentioning qgis for file-based reprojection is reasonable as a hand-off and does not imply hidden requirements.
Instruction Scope
SKILL.md instructs the agent to run the local script with explicit CLI arguments and to consult an included reference doc. There are no instructions to read unrelated files, access environment variables, or send data to external endpoints. The instructions are narrowly scoped to validating coordinates, guessing order, recommending UTM/CRS, and flagging China-offset risk.
Install Mechanism
Install spec uses a Homebrew formula to install Python 3 (brew 'python'), which is a well-known package source and appropriate for a Python-based skill. Note: Homebrew is platform-specific (macOS/Linux with brew); installing Python via brew may be unnecessary if python3 is already present and will modify the system's packages.
Credentials
The skill requests no environment variables, credentials, or config paths. The Python script operates entirely on CLI inputs and prints JSON to stdout; it neither reads secrets nor attempts to access unrelated system configuration.
Persistence & Privilege
Skill does not request always:true and does not modify other skills or system-wide configuration. agents/openai.yaml enables implicit invocation (allow_implicit_invocation: true), which permits the agent to invoke the skill when relevant — this is typical for utility skills and is not combined with other red flags.
